The Barrow-wights appeared as shadowy figures with a pale, icy light gleaming from what would be their eyes. They could speak, with deep, hollow and cold voices, and likewise their touch was icy.[5][6] They were furthermore infamous for carrying rattling gold-rings on their bony fingers.[4][7]

According to Hobbit verse, Tom Bombadil escaped a Barrow-wight on some occasion, using his enchanting incantations.[6] Perhaps his authority was sourced by the inherent power he had on this region of the world, not the spirits themselves.

During the War of the Ring, Frodo Baggins and company were trapped in the Barrow-downs by the spells of the Barrow-wights, and were nearly slain by the creatures.[5] They were saved in the last minute by Tom, who seemed to have had complete authority over them.

Names

According to Elrond, the Elves knew the Barrow-wights by many names.[8] While these names are not recorded (except for the general denomination "evil spirits"), the creatures were also called "Barrow-dwellers" in Hobbit lore.[6] Often, they were also referred to by the shortened form "Wights".[1][9]

Due to his inspiration from Hrómundar saga Gripssonar, during the writing of The Lord of the Rings (see The History of The Lord of the Rings) Tolkien at first foresaw a link between the wights and the Ringwraiths, initially describing the Black Riders as horsed Wights, but the suggestion that they were the same kind of creatures was dropped in the published work. In the final work there remained a link between them: the wights were now spirits sent by the Witch-king.

Sambrog is a Wight-lord of the Barrow-downs. Barrow Wights are not just confined to the Barrow Downs, but have risen in many parts of Middle-earth mainly around the decaying ruins of Arnor. Wights can be found haunting the darkest corners of Mirkwood to even the Elven ruins which dot Ered Luin. A clan of warriors in Dunland has even gone as far as trying to raise their own undead army.
